To all whom t may concern:

Be it known that I, ROY T. AXE, a citizenv of theUnited States, and aresident-.of Syracuse, in the county of Onondaga and State of New York,have invented a certain new and useful Spring-Roller, of which thefollowing is a specification. l

VThis invention relates to springl rollers for raising orcounterbalancing curtains, Windows, etc., which is particularly simpleand economical in construction andhighly eiiicient and durable in useand it consists in the combinations and Constructions hereinafter setforth and claimed.

In describing this invention, reference is hadto the accompanyingdrawings in.` -which like charactersl designate corresponding parts inall the views.

Figure l isa longitudinal sectional view, partly broken away, of aroller embodying my invention. A

Figs.V 2 and 3 are sectional-views taken ,vrespectively on lines 2 2,and 3-3, Fig. l.

lV designates the body of the roller, which is here shown as tubularthroughout.

2 and 3 are, respectively, the heads vatopposite ends Yof the body, inwhich are supported theaxles 4, 5, one of which as the axle 4 rotateswith the roller andthe other of which as 5 is held from rotation, sothat the body of the roller-revolvesaround'said axle.

6 is the spring connected at one end to the body of the rollerasghereinafter described, and at its other end to a portion of the axle`5, the spring tending to rotate the body of the roller aroundthe axley5.

Each head y2,3 consists of two -discoidal members, one of whichis-formed-.with a cylindrical flange which lits into oneend of thetubular body 1, and the other of which lies contiguous tothe formermember with its outer margin lapping the.,end edge of the tubularvbody 1. Each head Yis also formed withan opening for the axle 4.-or 5of the roller.

7 and 8 designate themembers of the head 2, ,the member 7 having acylindrical Yflange 9 which Vlits into the end of the-tubular body l,and 4the member 8v beinga fiat; disk,r the outer margin of which lapsat10 the end of the tubular body 1. The member 7 is held in position bysuitable fastening members as screws l1 extending through the wall ofthe body land into the cylindrical flange y9. Both members 7, 8 areformed with suitable central openingsfor the axle 4. Said axle 4consists of a rod'extending throughthe central openings of the members7, 8 of the head 2 and supported at its inner end by-a member12 littingthe tubular body 1 opposed to and spaced apart from the head 2. Asleevev 13 is inserted between the disk 12 and the discoidal member 7,said sleeve abutting at its ends against the said parts 7 and 12 andbeing located in alinement with the central openings thereof. The axle 4is provided with a flange or shoulder 14 abutting against the outer endsiof the member 8 of the head2andwith a shoulder l5 at its innerend'abutting against the inner face of the disk 12.

Preferably, the central portion of the disk 12 is projected toform a.spherical boss as shown at 16.

17 and 18 designate the parts of the head in which the. axle 5 -islocated, the member 17 being similar in construction to the member 7 ofthe head 2 butv having its central opening of larger diameter than thepart of the axle 5 therein. The member` 18 is similar to the member 8 ofthe head 2 but isl provided with a hub 19 which extends into the centralopening of the memberv 17 and which has its inner end spread in the formof a flange at 20 in order to form a peripheral circumferential groovein which-the margin ofthe member 17 around its central opening is held.

The outerA margin of the member 18 laps the end edge of the tubular bodyat 21.

The peripheries of both members 8 and 18 are substantially flush withthel periphery of the body l of the roller.

The axle 5 is provided with an annular shoulder 22 which abuts the outerface of the member 18, and said axle includes arstub portion locatedwithin the tubular body /1 anda tubularportion'23 mounted onthestublportion and` securedthereto by akey 24 purpose of the disk 27 is toreceive in one of the holes 29, a locking pin inserted through the holes30, 31 for the purpose of holding the spring 6 under tension: whent'heroller is dismounted.

The tubular portion 23 of the axle 5 is supported at its inner end by abearing or lug member 32 which includes a cup-shaped ody having atubular hub 33 projecting from its bottom 34C and in which the part 23of the axle 5 is journaled. Said plug member also includes a plate ordisk 35 inserted in the cup-shaped' member vagainst the bottom 34, thedisk being held in position by shoulders 36 on the cylindrical wall ofthe cup-shaped part. Said shoulders are formed by indenting thecylindrical wall at intervals so that the indented portions overlie themargin of the disk 35. The member. 32 is held in position by a key 37extending transversely through the body 1 of the roller Vand throughlengthwise slots 38 formed in the lmember 32 and opening through theedge of the cup-shaped part so that said member 32 can be removed andreplaced upon axial-movement thereof.

The spring 6 is connectedat one end to the axle 5 or the tubular portion23 thereof and at its other end to the member 32, it being here shown ashaving its extreme end portion 39 passed through a loop 40 provided onthe member 32. v
